Hang bird feeders among your fruit trees ... attract blue tits and great tits and long tailed tits ... within a couple of years they'll get used to visiting your trees for their food and they and their fledglings will hoover up your aphids.
Also don't use insecticides, as ladybirds, hoverflies, lacewings and other insects also prey on aphids.
in the first instance, if your hose will reach, turn a sharp jet of water onto the aphids and that will wash a good proportion of them onto the ground for your chickens.
Sounds a lovely orchard
